Dact / Goldpoint Installation Instructions
The following are the instructions to install and setup the remote control. Since the equiptment you are installing the remote control into will vary from installation to installation we will not cover that in detail here. A breif list of final installation guidlines is given at the end of these instructions.
Step 1 - Dis-Assembly
First remove the dact attenuator from the equiptment it is installed in. Set it on a clean work area. Now using a small flat blade screw driver remove the 2 small screws from the rear side of the Attenuator. Be carefull to not loose the small plastic spacers as these will be needed in step 2.
Step 2 - Install Motor Mounting Plate to DACT
The motor mounting plate is shipped attached to the stepper motor. Remove the 2 machine screws holding the plate to the standoffs attached to the stepper motor. Locate the 2 small screws shipped with the motor mounting plate and insert them through the mounting plate. Place the 2 small plastic spacers removed in step 1 on the small screws shipped with the mounting plate such that they will space the plate away from the circuit board on the back of the switch. Now attach the plate to the switch. See the Pics above for mounting details.
.
Step 3 - Stepper Motor Installation
Loosen the set screw on the motor to switch coupling so that the coupling will silde easily on the motor shaft but keep the coupling on the shaft. Now re-install the stepper motor using the #6-32 machine screws removed in step 2. Now slide the slot in the coupling so that in fits over the small tab at the back of the DACT switch and tighten the set screw a bit (but not too tight as we'll be loosening it again for adjustment shortly). Spin the switch about 10 times all the way clockwise and counter-clockwise. It should turn freely much like it did before the motor was attached.
Step 4 - Setup and Adjustment
Now for some fun stuff! Locate the remote control and power supply. Plug the power cable to the circuit board and then plug the adapter into a wall outlet. Press the level up/down buttons on the remote and confirm the motor spins the switch. Using the remote control run the switch up and down a few times.
Now we'll align the switch rotation with the motor rotation. Turn the switch so that the gold contacts of the switch are lined up with a step. Any step that is easy to see will do. For reference the switch in the pic above has been set to line up the contacts. Carefully loosen the set screw on the coupling without spinning the switch at all. press the up or down button on the remote to spin the motor shaft (but not the switch). When the motor is stopped tighten the set screw on the coupling. Now play with the remote and see if the switch stops on the center of the steps. If not just give it another go and after a couple of try's you'll get it to line up well.
Final Installation
That's it for the remote control unit but it won't do much good sitting on the table. The final step is to install it back into the gear it was removed from - along with the remote control board. Since all gear is different it's hard to get specific here but basically you need to install it such that you can route the remote control IR reciever to the front panel and fasten it there (Duct tape or a hot glue does a pretty good job of this). A small hole will need to be drilled in the front panel if there is no other spot for the IR reciever to 'peek' through.
IR extender cables are included so the board may be mounted elsewhere in the chassis. A hole will need to be drilled in the back panel to mount a power input jack. Wire this jack to the power terminals on the PCB soldering wires to the connector end and using the screw terminals on the PCB. If you have any questions about installation please feel free to call or e-mail for assistance.
